staging: zcache: misc build/config 



[PATCH V2 3/3] drivers/staging: zcache: misc build/config

Makefiles and Kconfigs to build zcache in drivers/staging

There is a dependency on xvmalloc.* which in 2.6.37 resides
in drivers/staging/zram.  Should this move or disappear,
some Makefile/Kconfig changes will be required.

	  Zcache doubles RAM efficiency while providing a significant

	  performance boosts on many workloads.  Zcache uses lzo1x

	  compression and an in-kernel implementation of transcendent

	  memory to store clean page cache pages and swap in RAM,

	  providing a noticeable reduction in disk I/O.
